The
rod of Asclepius (
⚕; sometimes also spelled
Asklepios or
Aesculapius), also known as the
asklepian,
[1] is an ancient symbol associated with
astrology, the
Greek god Asclepius, and with
medicine and
healing. It consists of a
serpent entwined around a
staff. The name of the symbol derives from its early and widespread association with
Asclepius, the son of
Apollo, who was a practitioner of medicine in ancient
Greek mythology. His attributes, the snake and the staff, sometimes depicted separately in antiquity, are combined in this symbol.
[2] Hippocrates himself was a worshipper of Asclepius.
[3]
Symbolism
he serpent and the staff appear to have been separate symbols that were combined at some point in the development of the Asclepian cult.
[4] The significance of the serpent has been interpreted in many ways; sometimes the shedding of skin and renewal is emphasized as symbolizing rejuvenation,
[5] while other assessments center on the serpent as a symbol that unites and expresses the dual nature of the work of the physician, who deals with life and death, sickness and health.
[6] The ambiguity of the serpent as a symbol, and the contradictions it is thought to represent, reflect the ambiguity of the use of drugs
[7], which can help or harm, as reflected in the meaning of the term
pharmakon, which meant "drug", "medicine" and "poison" in ancient Greek;
[8] we know that today antidotes and vaccines are often compounded from precisely the thing that caused the poisoning or illness.
Products deriving from the bodies of snakes were known to have medicinal properties in ancient times, and in ancient Greece, at least some were aware that snake venom that might be fatal if it entered the bloodstream could often be imbibed. Snake venom appears to have been 'prescribed' in some cases as a form of therapy.
[9] The staff has also been variously interpreted. One view is that it, like the serpent, "conveyed notions of resurrection and healing", while another (not necessarily incompatible) is that the staff was a walking stick associated with itinerant physicians.
[10] Cornutus, a philosopher probably active in the first century CE, in the
Theologiae Graecae Compendium (Ch. 33) offers a view of the significance of both snake and staff:
Asclepius derived his name from healing soothingly and from deferring the withering that comes with death. For this reason, therefore, they give him a serpent as an attribute, indicating that those who avail themselves of medical science undergo a process similar to the serpent in that they, as it were, grow young again after illnesses and slough off old age; also because the serpent is a sign of attention, much of which is required in medical treatments. The staff also seems to be a symbol of some similar thing. For by means of this it is set before our minds that unless we are supported by such inventions as these, in so far as falling continually into sickness is concerned, stumbling along we would fall even sooner than necessary.
Asclepius: A Collection and Interpretation of the Testimonies, Baltimore, 1945
In any case the two symbols certainly merged in antiquity as representations of the snake coiled about the staff are common. It has been claimed that the snake wrapped around the staff was a species of rat snake,
Elaphe longissima.
[11]
[edit] Biblical
A similar symbol,
Nehushtan, is mentioned in the
Bible in the
Book of Numbers (Numbers 21:6-9).
Then the LORD sent fiery serpents among the people, and they bit the people, so that many people of Israel died. And the people came to Moses and said, "We have sinned, for we have spoken against the LORD and against you. Pray to the LORD, that he take away the serpents from us." So Moses prayed for the people. And the LORD said to Moses, "Make a fiery serpent and set it on a pole, and everyone who is bitten, when he sees it, shall live." Moses made a bronze serpent and set it on a pole. And if a serpent bit anyone, he would look at the bronze serpent and live.

[edit] Medical
A direct representation of ancient traditional treatment of
Dracunculus medinensis, the winding worm of death. The worm peeks out of ulcerous blisters to lay eggs, primarily when the wound is placed in water to cool and soothe it. The practitioner would pull the worm out slowly by winding it around a stick.

The EMS
Star of Life features a rod of Asclepius
A number of organizations and services use the rod of Asclepius as their logo, or part of their logo. These include:
[edit] Confusion with the caduceus
Main article:
Caduceus as a symbol of medicine
The
U.S. Army Medical Corps Branch Plaque. In 1902 the
caduceus was added to the uniforms of Army medical officers.
It is relatively common, especially in the United States, to find the caduceus, with its two snakes and wings, used as a symbol of medicine instead of the correct rod of Asclepius, with only a single snake. This usage is erroneous, popularised largely as a result of the adoption of the caduceus as its insignia by the
US Army medical corps in 1902 at the insistence of a single officer (though there are conflicting claims as to whether this was Capt. Frederick P. Reynolds or Col. John R. van Hoff).
[14][15]
The rod of Asclepius is the dominant symbol for healthcare professionals and associations in the United States. One survey found that 62% of healthcare professionals used the rod of Asclepius, while 76% of commercial healthcare organizations used the caduceus.
[16]
The initial errors leading to its adoption and the continuing confusion it generates are well known to medical historians. The long-standing and abundantly attested historical associations of the caduceus with commerce, theft, deception, and death are considered by many to be inappropriate in a symbol used by those engaged in the healing arts.
[15] This has occasioned significant criticism of the use of the caduceus in a medical context.
As god of the high-road and the market-place Hermes was perhaps above all else the patron of commerce and the fat purse: as a corollary, he was the special protector of the traveling salesman. As spokesman for the gods, he not only brought peace on earth (occasionally even the peace of death), but his silver-tongued eloquence could always make the worse appear the better cause. From this latter point of view, would not his symbol be suitable for certain Congressmen, all medical quacks, book agents and purveyors of vacuum cleaners, rather than for the straight-thinking, straight-speaking therapist? As conductor of the dead to their subterranean abode, his emblem would seem more appropriate on a hearse than on a physician's car.

For example, the first-century CE historian Lucan writes that the younger Cato, when leading his troops through Libya during the Roman Civil War, informed his men about this very point [...] 'The poison of snakes is only deadly when mixed with the blood; their venom is in their bite, and they threaten death with their fangs. There is no death in the cup.'" He also mentions an account of Cornelius Celsus (first century CE) "'For a serpent's poison, like certain hunter's poisons..., does no harm when swallowed, but only in a wound'". "Likewise, Galen relates a rather peculiar healing by Asclepius involving viper's venom. The god appeared to a wealthy man in Pergamum and prescribed 'that he should drink every day of the drug produced from the vipers and should anoint the body from the outside.' [...] The elder Philostratus describes a similar practice of 'the wise Asclepiads,' who 'heal the bites of venomous creatures... using the virus itself as a cure of many diseases.'"
